Hi everyone,
i just bought a (not new) 16g Transformer Tablet (FW3.1) which has finally arrived today.
The pre-owner told me the transformer got a Custom ROM. (MoDaCo) Unfortunately the tablet isnt working correctly.
After turn-on, the Transformer shows up the Eee Pad Logo and Asus logo on the bottom, but doesnt boot up to anything else. The restore-Function (Power+Vol down - told from Asus) does not work for me.
If im trying to power off the device, the screen turns off for apx. 5 seconds and the device just reboot back to the asus / eee logo. So i cant even turn off the device. The USB Port seem to work, Windows 7/x64 gives a plugged-in-noise when the Transformer is connected, but theres not storage device shown.
Can somebody help? Maybe a hard-Reset or full-restore without asus software?
thanks for help!
Hi, got exactly the same problem, and I am not only the one... definitely an issue with the 3.2 HC update. Just trying to fix at the moment... will appreciate some help from the Phorum...
I had the same thing happen, although I had put my own cwm into the stock 3.1 rom.
However if you had a custom rom/boot loader and tried running the OTA update - you will have issues.
First, press vol_down with power button hold for a while, then you should eventually get a screen (If you're not even more hosed than I was) that says press vol_up to wipe, vol_down to cancel. do either, and then it will cold boot linux, and you should be working as long as you don't want to update again.
If you do want the update (I did) what I had to do was do a full nvflash (look for transformer unbricking threads) of a stock image - those are also available on xda threads.
Once you have done that, I personally had to then use microSD SOP update from ASUS, so that future OTA updates would be recognized. So do the standard ASUS offline microSD install of the latest 3.1 build.
Finally you can ota to 3.2 and then mod/root from there.
All of this changes if your serial number starts with b70 (Mine does not) but I do know b70 builds have other issues with the boot loader, that may cause issues.
Thanks pal, I am trying a factory reset (could access by button volume - power combination) but it's seems to be taking ages (40 minutes and accounting with the "it make take a few minutes" screen) Is it normal? How long does it take a cold reset?
Factory reset also fails at that point. If I understand correctly, using the power/vol down got you back into the OS, from the settings app, you did a factory wipe?
That also will not work. Once you're back up and running via power/vol_down - you need to do a NVFLASH of EVERYTHING. Even the factory wipe seems dependent on things that get overwritten when you try an OTA over a CWM'd device.
Once you have the stock back in place, then factory wipe etc will work, but using nvflash to replace everything will accomplish essentially the same thing.
Here is the link for the stock roms I used:
http://www.transformerforums.com/fo...nsformer-nvflash-stock-3-1-recovery-roms.html
@akameswaran -> Thanks for the Hint!
I´ve downloaded a Stock Rom 3.1 from Tabletroms.com with NVFlash included. So it was rather easy, after installing APX Drivers (nVidia Restore / Recovery Device USB Drivers) you can just use the prepared NVFlash to send the Boot, System and Kernel ROM Files automatically to the transformer.
All data on the tablet has been deleted, but its now back on 3.1 factory defaults and working fine. Theres also use a MoDaCo Custom ROM, put into the NVFlash Folder, to re-flash the device with modified roms.
However, thanks everyone!
What could it possibly mean if even NVflash back to stock doesn't work? I can't get to Honeycomb at all. :'(
It just turns off right after showing the Eee Pad logo for 1-2 seconds. I
Can you connect the tablet to the PC and get it recognised? Go to device manager and see if there is a device with exclamation mark.Load the drivers and flash via Nvflash.
APX mode works fine, as does the flashing process. It just still won't boot even with the stock ROM.
I've found that since the US 84411 rom having the wrong bootloader may cause the transformer not to boot with other roms.
I'd suggest trying to nvflash to 3.2 stock again but first replace bootloader.bin in your nvflash folder with the one in the attached zip file.
is or was your transformer also making a some sort of ticking sound?
because my transformer is also hanging on that eee pad logo, i'll think also after installing a new clockworkmod recovery.
Ok like an idiot I went to install the stock Asus rom over my AKOP rom using twrp. Now it just sits at the Asus logo screen and will not boot. How the hell do I fix that?
If you still have fastboot flash cwmand do it again
And if I don't have fastboot? I mean right now if I hold vol down and pwr all it does is turn the screen off. It will not boot into twrp

Turn the screen off? Screen shouldn't be on when you do it, shut it down, then hold Power+VolDown until it turns on and the white text comes up in the corner.
then you will see 3 icons choose the usb icon with Vol- and Proceed with Vol+. Then you are in fastboot.
I got it thanks! She's back up and running.
Hello,
I also have the problem to get stuck in the boot screen. I have a brand new TF300TG, only installed some apps (not unlocked, not rooted). I only made the automatic update to 9.4.4.40, after that it always stops at the boot screen.
What I already tried:
- cold boot
- wipe
- RCK (Android with rotating things shows up short, after that the Android with the warnings sign shows up)
I also downloaded the whole WW 9.4.4.40 package from ASUS and put it on a MicroSD. If I make RCK with this (if I rename the file to EP201_768_SDUPDATE.ZIP) the Android with the rotating thing shows up longer, but I still get stuck in the boot screen.
I already contacted ASUS support and will also return it to a service center, but I'm in China and expect a long process with some troubles, so I wanted to ask if anyone has another idea what I can try?
Ernst
Update:
I think it was now possible to update WW 9.4.4.40 again (renamed to EP201_768_SDUPDATE.ZIP). I now used a different MicroSD with only 2GB. The first time RCK it stopped in the middle of the update (after that the Android with the warning sign came), the second time I tried it, I think it finished, but the TF300TG still stops booting at the ASUS boot screen.
If I try now to update over MicroSD again, it doesn't work.
I have the same problem, only difference is that pressing vol down and power on makes no difference. When its on I also can't turn it off. I just have to wait until the battery is drained.
you have flashed ICS ROM in JB bootloader as far I see - hardbrick if you don't have nvflash files - only service.

Its not me Its the Drivers!!!
So I have a TFT300T, unlocked and rooted, all was fine till i decided to try another ROM. So I installed CWM no problem. Once I installed the ROM problem. I seem to be stuck at the ASUS screen. I have tried loading boot loader to do a wipe and factory reset and that simply boots me to CWM, tried the same thing there but to no avail. So researched bricked Transformer and came across the Nvflash method as well as the Asus Transformer Kit (US ONLY). However I cant proceed cause of the APX driver issue. I tried the included drivers but Win7 wasn't interested. I tried 1 desktop and two laptops, same thing. I even tried my bench tester. Now Universal_Naked_Driver_0.72 seems to install but no communication between the PC and the tab with this driver.
I tried bootloader to try a fastboot command but then the Device manager demands a driver for "Transformer". Same issue. Tried downloading from Asus plus a couple on the web. It seems its the Tablet. I thought to try CWM and an sdcard but it doesn't give me the option to mount it. So if any one knows a fix I would be forever grateful.

I also found the asus transformer kit(us only). But the same problem. I am able to connect my tablet with apx mode, in my device manager I see apx device. but in the tutorials it says that I have to force install de driver, but I don't know which driver to install. I tried the asus driver and every file in the asus transformer kit but nothing. I triend the universal_naked_driver but I can't get it to install can anyone tell me how to proper install that?
Ok to start I have rooted my device and unlocked the bootloader. My device worked fine till I came home and tried to turn it on and it wouldn't wake up. So I held down the power button till it viberated and rebooted. Then the device got stuck at the ASUS screen. So i held down the power button and down volume and tried to boot into recovery. My device reboots with the following message:
The Device is UnLocked.

Hope your bootloader can read it.

I can't get into boot loader. I was reading about NVflash and it does recognize my device with APX. I have the US_epad_user_9_4_5_22_UpdateLauncher.zip which is the US firmware. Is it possible to flash this by nvflash?
So is the bootloader/recovery that you flashed the one from this thread? If so, perhaps it would be best to ask (either in the thread or PM) the OP.
No its the stock bootloader. All I've done is unlock the bootloader and root the device. That it.

First off this is a question not a development topic so you are in the wrong section. That aside it maybe worth contacting Asus and seeing if they will help you even though you unlocked your device because if what you say is correct it sounds like it is their software that messed up your device. I hope you can find a way to fix it. It would be a shame to have such a pretty brick!
Moved to Q&A.
Reading through different forums I have read problems similar to mine but nothing exactly the same. I followed each fix anyway but I have not been successful.
The last thing I remember I did before the brick, I flashed CWM touch then CyanogenMod 9. I am unsure what occurred but I tried to flash back to my JB backup and the problem started.
Now my tablet comes on and just hangs on the Asus splash screen. If I turn the tablet off, it automatically comes back on.
I have tried to turn the tablet off and boot into recovery but it just boots back up to the splash screen and hangs; I have no option to go into recovery, android or fastboot.
I can get into what I think may be USB mode by pressing power and volume up through a couple of cycles; my computer detects a device but I cannot load drivers.
I have downloaded the Android USBPCdrivers but each time I try to navigate to the folder to install the device manager fails.
If anyone has any thoughts I would appreciate any assistance, thanks for your time!
UPDATE TO ORIGINAL POST
I as able to finally get my computer to recognize the tf300t in device manager by wiping all the usb drivers and installing "Universal Naked Driver 0.7" posted by 1wayjonny from XDA's website http://forum.xda-developers.com/show....php?t=1766220, not sure if it matters my computer "sees it" as a ASUS transformer prime rather than tf300t.
Now I am reviewing an ASUS unbrick called Wheelie http://forum.xda-developers.com/show....php?t=1687285, I believe this is geared towards the tf101. Anyone have any thoughts based on my status at this point? Thanks
If you are on JB stock, there is no way to flash a booting Cyanogen 9 ot 10 Rom.
Only Hydro JB is running!!!! And JB Stock.
1st of all you have to download a special Recovery. I highly recommend TWRP. You have to dl the JB version!!!!!
Flash it through fastboot. Then flash the Stock JB via TWRP recovery
Then flash TWRP again via fastboot.
Than flash The Hydro JB rom
Then reboot
Then go back to recovery
Then flash the latest Hydro update and reboot
You are like me stuck on the f...... new JB Bootloader and Kernel. All other roms are for the ICS Bootloader and Kernel, so no way of getting them running until the Cyanogen devs finding a solution.
Fastboot not an option
Thanks for getting back with me.
Fastboot is not an option for me; the tablet hangs on the splash screen.
I can get into the usb mode but I am unable to locate any APX codes to push anything over. The only codes I can find are for tf100 & 200 moddels.
Any thoughts?

You're hosed.
The developers that worked on the prior TF units' nvflash said the development isn't done on the TF300 yet. And, even if it was, you needed to perform some steps prior to bricking the device to make APX accessible after a brick. If your device is bricked already, your only recourse is to send it to Asus and eat the $197 fee to have your motherboard replaced.

i have the same problem, and only APX mode is accessible, (no fashboot, recovery..) can get chip ID from APX mode, that is all,
should i wait for the nvflash rom(about 3-4 weeks, is that right?), or paid for this? (replace the motherboard)

Waiting for nvflash won't do you any good since you needed to have it BEFORE bricking your tablet. If your tablet is already bricked, APX/nvflash will not help you.

He could still try sending it for RMA. Mine got repaired for free for some reason.
An unusual Asus TF300T brick
Yeah, I'm having problems with my TF300T, too. I had CWM installed, but when I tried to flash a new ROM, I bricked it. No problem, I had figured it out before. But when I was in the bootloader, I inadvertantly erased instead of selecting the USB. Now, All I get when I try to boot up is the white ASUS screen with;
The Device is Unlocked
Android cardhu-user bootloader <2.0 e> released by "ww_epad-9.4.3.26-20120416" A03

My computer sees the tablet. The Device Manager shows: Asus Transformer Prime APX Interface
But it only shows up when I reset. As soon as I try to boot the tablet, it no longer sees it. I can't access the bootloader and Fastboot doesn't do anything except "waiting for device".
SO! If anyone can give me some help, I'd appreciate it. It's a puzzle for ya, anyway.
Thanx
As your last resort, this worked for me

I have messed around with all my electronics in the passed, rooted them, put custom roms etc. with no trouble. So after getting frusterated with my Asus TF700T, I decided it was time to put Cyanogenmod on it. I read up on the forums and it recommended TWRP, I have always used clockwork mod but because TWRP was recommended I used that. I followed the directions and rebooted to the startup and it is stuck on the Cyanogenmod startup screen. So thinking that maybe it was just taking a long time because it was the first time, I waited and waited and waited. 24 hours later still stuck on the startup screen. I decided to try again, I pressed the power button and the volume down button and this is what I see:

When I press volume up once to select RCK I get a message stating:

After reading I decided to try tranformer tool kit. So I put the tablet into APX mode.

Evidently I screwed things up somewhere but I don't know where to go from here... Please, If anyone can help, It would be so appreciated.
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck
I sounds like the recovery flash failed. If you haven't already, I would try to re-flash TWRP through ADB and fastboot.
If you aren't sure how to do that through ADB use this post:
http://forum.xda-developers.com/showthread.php?t=2688891
Its the beginners guide in the general section.
I may be wrong here, but I've taken my TF700 from the brink of death and back again a few times.
What TWRP version did you flash and how???
The unrecoverable bootloader error is not good news. Usually you need a buster99 to get your tablet back - if you still can get into the bootloader and fastboot.
If you can, follow the instructions below to the letter (naturally you have to flash the TF700 system blob, not the TF300!), then flash a compatible recovery and a rom compatible with your recovery and bootloader. And if you're not sure ask first, then flash....

Ummmm let me take a wild guess what customer support will advise:
Sorry you unlocked so no warranty but send it in and for $300 we may repair it. If we can't we only charge you for shipping both ways.
Nice to see you, Asus! Where've you been the last 2 years?

Yeah - I had that dream too one time or another....
Hi all, I just encountered this same error message for the TF700T when going into fastboot mode
Key driver not found.. Booting OS
Android cardhu-user bootloader <1.00 e> released by "US_epad-10.6.1.14.10-20130801" A03
Starting Fastboot USB Download Protocol
All I have done is unlock the tablet. I was on the "Practice/Background" step in berndblb's (awesome) custom ROM guide before starting to load up fastboot and adb, when I saw the message in the upper left corner. When I go into RCK, "booting recovery kernel image" then appears under the error message. After 3-4 seconds I get the dead android with "error!" screen. When I power off, the tablet goes into normal bootup and the stock ROM still works perfectly fine.
Since it does, is there something I should do to resolve this issue BEFORE trying to push TWRP to the tablet? Just trying to be prudent...
Many thanks,
MM
Every Asus tablet I have seen has the "key driver not found" on boot - ignore it.
The dead Droid also is perfectly normal. It's the stock recovery not finding a firmware file to flash. Just keep going
